It really is a great game. Had it for quite some time without playing it and decided to give it a go recently. Played nothing else for weeks making my ice castle haha.
I started again last night. There's so much new stuff! I found the backgrounds to change a bit too quickly in my world, though, so I had to turn them off, which was a shame, since I thought the parallax scrolling looked really cool.
I haven't had that problem on any of my worlds and it does look really cool :P
